Earth Science — Tier 3 Catalogs

Encyclopedic reference catalogs behind the Tier 1 surveys of the Earth Science library — the enumerated inventory layer (minerals, rocks, the time scale).

Catalogs in this folder

• minerals-catalog — ~210 minerals by Dana/Nickel-Strunz chemical class (silicates by structure, native elements, sulfides, oxides, halides, carbonates, sulfates/phosphates, gems), each with ideal formula, crystal system, hardness, and occurrence. Companion to mineralogy.
• rocks-catalog — ~135 rock types across the three families (igneous intrusive/extrusive, sedimentary clastic/chemical, metamorphic foliated/non-foliated, plus extraterrestrial), with composition, texture, and formation. Companion to igneous-and-metamorphic-petrology and sedimentology-and-stratigraphy.
• geologic-time-scale-catalog — the complete ICS time scale (eon → era → period → epoch → age) with absolute dates, boundary events, and the life/Earth conditions of each interval, plus the Big-Five extinctions. Companion to geochronology-and-geologic-time.
